Well, I've seen lockups (no ping) on my machine as well from time to time.
It's using XF86_S3V, it has some Diamond graphics card (can dig
out exact name if needed).
It happens just occasionally, happened recently twice when I had shutdown
X-windows, no heavy load.

It is better never to have been born. But who among us has such luck?
One in a million, perhaps.
